[0006] To achieve the above purpose, the utility model provides the following technical scheme: a contrast agent preparation device, including:

[0007] A preparation barrel for contrast agent preparation, and a top cover is installed on the top of the preparation barrel;

[0008] An inner barrel is arranged inside the preparation barrel. A discharge pipe with a control valve is fixedly inserted at the center of the bottom of the inner barrel, and the discharge pipe is movably inserted on the corresponding side of the preparation barrel. A first motor is installed on one side of the bottom of the preparation barrel, and a gear pair is installed between the output end of the first motor and the corresponding side of the discharge pipe. One side of the bottom of the top cover is connected with a connecting plate, and a plurality of bristles that abut against the inner wall of the inner barrel are evenly adhered to one side wall of the connecting plate. A bent water inlet pipe is inserted into the upper part of one side wall of the preparation barrel, and one end of the water inlet pipe is connected with a spray head corresponding to the inner barrel.

[0009] In a further embodiment, an adding pipe is inserted into one side of the top of the top cover, and a second motor with an output end turning in the opposite direction to the first motor is installed at the center of the top of the top cover.

[0010] In a further embodiment, the output end of the second motor penetrates through the top cover and is coaxially connected with a rotating shaft, and a plurality of stirring blades are evenly connected to the side wall of the rotating shaft.

[0011] In a further embodiment, two handles are symmetrically connected to the top of the top cover, and the edges and corners of the handles are in an arc-shaped structure.

[0017] For this contrast agent preparation device, although the existing device can efficiently complete the stirring and mixing of the contrast agent, when the inside needs to be cleaned, it requires manual cleaning of the inner wall of the inner barrel, which is undoubtedly not convenient enough. In this solution, the inner wall of the inner barrel can be continuously sprayed with clear water through a spray head for flushing, and at the same time, the inner wall of the inner barrel will be cleaned by the brush bristles when rotating. Through the cooperation of clear water flushing and brush bristle cleaning, the inner wall of the inner barrel can be efficiently cleaned, further improving the efficiency;

[0018] When preparing the contrast agent, the inner barrel is driven to rotate by the first motor, and at the same time, the stirring blades are driven to rotate in the opposite direction to the inner barrel by the second motor. Through the cooperation of the above structures, the raw materials of the contrast agent can be efficiently stirred and mixed;

[0019] When further maintenance of the internal structure is required, only by screwing out the top cover, the second motor and related structures can be taken out, and at this time, the inner barrel will be exposed, and then the internal structure can be conveniently maintained, and the maintenance is relatively convenient;

[0020] This contrast agent preparation device can efficiently clean the inner wall of the inner barrel to further improve the efficiency. Brief Description of the Drawings

[0039] For this contrast agent preparation device, connect the device to an external power supply. First, the raw materials for preparing the contrast agent can be put into the preparation barrel 1 through the addition pipe 17. Then, start the first motor 4 and the second motor. Under the action of the first motor 4 and the second motor, the inner barrel 2 and the multiple stirring blades 12 rotate towards each other to efficiently stir and mix the raw materials of the contrast agent. After mixing, turn off the first motor 4 and the second motor, and then open the control valve to discharge the contrast agent through the discharge pipe 3.

[0040] When it is necessary to clean the inner barrel 2 to prepare the contrast agent again, connect the water inlet pipe 8 to an external water supply pipeline, and turn on the first motor 4. The first motor 4 drives the inner barrel 2 to rotate continuously through the gear pair 5, so that the bristles 18 can continuously clean the inner wall of the inner barrel 2. At the same time, input clean water through the water inlet pipe 8 and spray it onto the inner wall of the inner barrel 2 through the nozzle 9. The cooperation of the two structures can efficiently clean the inner wall of the inner barrel 2, and the cleaned water can be discharged through the discharge pipe 3.
